I think this is excusable. People will make mistakes when they are emotional, and then they will blame themselves and regret it. If you forgive him at this time, he will certainly remember this lesson and pay attention to his behavior at any time. Everything is two-sided. If there is no bad thing, it will become a good thing, just like this quarrel. Wouldn't it be a good thing if he remembered to remind himself not to make mistakes again? Be bigger and understand a little.
